Hen tycker om jackorna!
I'm pretty sure that hen is the gender neutral singular pronoun. Plural would be de which is already gender neutral by default.
tycker om is actually used as the romantic like
When talking about people. When talking about things it jusy means "like".
What is the difference between, "de", and, "det"?
de är= they are
det är= that's
What is the difference between "gillar" and "tycker om"?
None. Gillar might be a tad more colloquial.
I used gillar and it was not accepted
how do we know which one to use when translating?
Both are accepted.
